The hon. Gentleman leads me to my next point.
The current situation is the wrong way around. It should not be easier to buy land, do nothing, aim to get planning permission and then flip for a profit than it is to build houses. From a moral and an economic standpoint, design and construction should be the things that add value to land, not hope or speculation. Planning permission is a huge and value-creating decision. The decision is taken by each local community, so they should see some of the value that is created. We need a tax on the speculators’ profits, paid straight to local councils on the day that planning permission is given or changed, in order to fund the local services that turn dormitories into communities.
